Launchbox Version 11.17 crashing with updated metadata.xml

[Thomas Senoner]

Since January of this year, I've been experiencing an issue with "Launchbox Version 11.17 crashing whenever I add and tag a new game *after* downloading a database update (metadata.xml).

When I restore an old metadata.xml (from December 2023) of a backup, everything works fine again. The problem is reproducible directly; If I install Version 11.17 on another PC, activate the license, and I can add games. All good. But as soon as I perform the database update, Launchbox immediately throws the error message whenever a new game is tagged and crashes.

 

This is the error message:

Note: The current version of Launchbox does not have this issue. Apparently, there has been a change in the structure of the metadata.xml file.

I also liked the light operation of version 11 and used it until the other day, but I had no choice but to update to the latest version because I faced the same problem.
I considered it as the de facto end of support😄

I unfortunately suspected something like that already. Really unfortunate.
